With the Hammers keen to boost their attacking options, the club have been trying to come to terms with the Italian side over a deal for the winger.

Agreeing a fee for the 25-year-old has always proved to be a sticking point, yet Italian publication Gazzetta dello Sport now claim that a fee in the region of €40million has been agreed between the clubs.

While Anderson will no doubt be a big loss to Lazio after some impressive performances since his move from Santos in 2013, reports from Italy suggest that they are already eyeing up a move for Sporting Lisbon ace Gelson Martins.

Linked with a big-money move to Arsenal and Liverpool recently, the Portuguese ace could potentially be available on a free transfer having asked to be relieved from his contract with the Primeira Liga club.

Rui Patricio sealed a free transfer move to Wolves last week, while the club also face the real prospect of losing star players William Carvalho and Bruno Fernandes for nothing.

Corriere dello Sport claim that Lazio have made contact regarding a deal for Martins and the player would be keen on a move to the Italian capital.
